Power-supply noise, Part 2
Part 1 looked at the basics of noise, especially concerning power supplies. There are two noise sources which are not as obvious to many engineers as noise that results from the switching action of the power supply: differential mode noise and common-mode noise. These two noise modes have different causes and thus different solutions Q: […]
Magnetically shielded, SMD coupled power choke sports low dc resistance
WE-DPC HV (Double Power Choke High Voltage) is a magnetically shielded, SMD coupled power choke with two identical windings and a high isolation voltage of 1.5 kV. It is the smallest product of its type in the Würth Elektronik eiSos portfolio. With this power choke in a 5030 package, customers can attain a 40 percent […]
